:This invention-:relatesto locks and has particular reference to locks `,usedto secure a spare tire and its rim to 'an rautomotive vehicle.

35 Itis an object of the invention to construct a simplified lock which has' a housing or covering which prevents access to the usual nut which secures the 'bolt and clampl`! and the tire rim.. l

In prior constructions the h-Ousingswhich `havef'usually 'protected the `securing nut from 4access have been made either entirely 'removable orformed fa rather complicated portion `of the lock or clamping means. In

the present invention 4the closure or 'housing is pivoted to a locking lug and to secure the housing, the hinge orpivot ,pin is locked to both of the hinged parts.

closure orhousing 'instead of `being locked at its pivot 'or hinge connection is locked by causing thel locking bolt to `catch behind a projection or linger on the clamping member 15x25 which projection is preferably immediately over the securing bolt.

IReferring to the drawings:

Fig. 5 is a sectional view on the line Y5-45 of Fig. 4. f

Referring to the drawings, numeral 2 indicates a bar `secured across the rear of an automotive vehicle. To the bar there is s ecured by means of ythe sleeves or collars 4 a pair 'of arms 6` which are secured bymeans of rivets 8 to a frame 10 whichv is preferably' in the ormof a ring. The frame lO-is provided with' the web 12 and the lateral flanges 14 fand v16. The flange 14 -is inwardly/turned as shown at 18 to :accommodate .a parthof the lockingmember, or rims Ehaving projecting portions, while totheweb .As a modification of the invention the l l2 there isisecured `byineans` of tlhedrivets`Y "20 a lflange! or 'clamping arm l22. This clamping arm 22 has preferably a broa'dend of the rim 26-1a's is shown in Fig.. 2.

and is adapted to 4kengage the-rear 'fla-nge 24 The rivetsy20 :also secure itotheframe l0 e ya bolt 28 having its free 4or 4threaded Iend..3 0 `projecting well outwardly-beyond the framer ing member againstV the tire carrying .frame Vl0 f bot-li sidesxof the vbolt 28 and is provided' with a recess -3'7 to allow for the ,extension 30fof the bolt 28.@ l

Adjacent the outer flange '14 andi the racket ,32 there is 'mOuntedxt-he clamping Farm Or lug36 provi-ded with anbpeningxBS to allow `for the passage-of the threaded end 30 ofthe bolt. vThe lower portionof fthe :clamping arm 316 is" provided with :a

`finger 40 which `strikesagainstl the outer flange '42 "of the Yrim 26. n The finger is pret- 'erably broad and is provided With an in- Wardly' projecting' portion `44 which is adapted `to fit lover the Webof the rim 26 .and vagainst' the inwardly flanged portion j 18. `The upper portion of the yclamp 36 is provided with' la projection 46 which is 'adapted toyabut against the `upper portion 34 of the bracket32 to properly position the lug 36. i

A nut-or operating member 48 is screwed on to the threadedend l30 of the bolt 28 and in. its iin-al `position as shown in Fig. 2 willrigidly clamp orhOld-the lug 36 against the bracket 32 and rim. 26to rigidly hold the parts in position.

.eo Y

The upper portion 0f theiugee istifu'e,

cated as indicated at `5() `and lbetween ,the furcations there isv .positioned the ear .52 of a housing "Or-covering 54 which is adapted f Shown in `Figsfl and l2.

'95 lto lit over and house the nut 48.` The lug y i 2ik The pivotal connection betweenr the f furca- Y tions 50 and the ear 52 is formed by a hinge pin 58, preferably though not necessarily rigidly mountedV in oneof the forks 50, and a lock barrel 60 which are seated in suitable openings provided in the furcations 50 and the ear 52. The hinge .pin 58is pro- Y vided with a recess 59 in which there is adapted to slide the locking pin 62. 'Ihe locking pin'is urged by means of a spring 64 out of the recess and intoan opening 66 in the upper portion of the clamp or lug` 86. The pin is'provided with a recess or cut out portion 68 for thereceptionof an'.

eccentric pinO on the `end of the locking barrel 60. By means vofja suitablegroove 2 and pins 7 4 the' lock barrel 60 isl rotatably held in its pivotal connection and from an examination of Fig. 3 it will be apparent that by turning the key'? 5 the eccentric pin 70 will withdraw vthe pin 62 vagainst the tension of the Vspring 64 out of the opening 66 and permity the rotation of the housing member 54 on its pivotal or hinged axis.

If desired a single hinge pin with'. a rotatable locl barrel therein may be used and the locking pin 62 operate in a recess or opening in the hinge pin or the hinged connection may be made in two parts rigidly Vsecured to thefurcations andV with therecess 59 split between the parts Yanda separate rotatable lock barrel applied inthe hinge member 60. The position of the parts when in their locked relation is shown in Figs 2'and 3. Y From a consideration ofthe position of the parts as shown it-will be apparent that 'any effort made to vswing the housing 54 on its .pivot will be prevented by the locking pin 62, due to its engagement in the opening 66, or across the pivotal. surface. After the locl barrel and its eccentric pin 70" have withdrawn the locking pin' v62 inside the recess 59 in the hinge' pin 58 the pivotal connection will be free orV unobstructed which will permit the housing 54 to be'swung upwardly and render the nut 48 accessible for the-'application of a wrench or other suitable tool. the clamping lug 86 and its connected housing and locking means maybe Withdrawn,

which will permit the withdrawal of the ri1n'26v from the' frame 10.

eferring to'the species of Figs. 4. and

` 5,' it will 4be seen that the hinge pin 58 is i' 'ofordinary type and does not have a lock embodied therein as shown in the species of Figs. 1 to 3 inclusive. vThe frame or sup.-

port'l-OV is provided with a flange 79 and insteadvof the (bracket 32, use is made of a Vclamping member 80. which extends in.-

wardly over the inner periphery ofthe frame 1 0! as shown at w82. ,The lower portion184 is `hook-shaped as `shown at 86 and fits over the edge of the `flange 42 offthe rim 26.

After the nutv has been removed The front portion of the clamp is open as shown at 88. Y

The frame 10 is yprovided with openings in which there is received the bolt The head 94 of the bolt abuts against one side 96 of the frame 10-While thel threaded end 98 extends pastvrthe oppositeside ofk the frame as shown in Fig. .5. The flange 79, it will be noted retains onev side of the rim 26 on the support or frame'10.

The clamp 80 is provided with Va transverse portion 10() having an opening 102 for the reception of thethreaded'end 98 of the bolt 92.l A nut -104is screw threaded on' ythe end 98and in the position of the parts holds the c lamp shown in Fig. 5, rigidly 8O on tothe frame 10 and'rim 26'.

Y' A. closurelOG isV pivoted vkat 104.- The closure v106 fits rather closely into the opening 88 ofthe clamp'80 to prevent 'the insertion of a sharp tool.

For purposes of clearer illustration the closure 106 has a relatively wide spacebetween its edge and "e the edge of the opening 88. K

:A lock barrel 110 's secured with; the

closure 106 and has the locking` bolt 112.

the bolt 112 from behind the Yprojection 114. This will permit the swinging of the closure -106 on its hinge 58 which willexpose' the nut 104 to view and permit thefapplication the nut. After the'nut is unscre'wed the g `clamp 80 may be bodily removedv forfthe reason that it has nork other; means-for secur-r ingritto the rim or frame.
